Title: Method of joining workpieces by means of a beam of charge carriers
IPC: B23K15/00
Filed: 1963-02-21
Abstract: Workpieces are joined by the use of a bonding material which is fused by a beam of charge carriers.  An electron or ion beam which may be continuous or intermittent is directed on the bonding material in the direction of the plane of the joint and is focused to fuse the bonding material and a thin layer of one or both workpieces. In this way metal may be bonded to glass using a metal or a glass or vitreous bonding material added in a solid strip or in powder form, or two metals joined by the vitreous material.

Title: Traffic control systems and apparatus
IPC: G08G1/082
Filed: 1936-03-09
Abstract: 459,754. Road signals for controlling traffic. AUTOMATIC SIGNAL CORPORATION, 230, Park Avenue, New York, U.S.A.- (Assignees of Eames, E. H.; Old Greenwich, Connecticut, U.S.A.) March 9, 1936, No. 7026. Convention date, March 14, 1935. [Class 118 (ii)] In a system in which right-of-way is normally with a main road and a side street is given a chance to obtain right-of-way in each cycle of a master unit, if the main road retains the right-of-way for more than a predetermined number of cycles, or more than a predetermined time, a call from a cross street is at once effective to initiate transfer of right-of-way. The signals are controlled by a rotatable cam shaft, the cams being divided and adjustable so that the division of the cycle can be varied. The camshaft 21 is normally at rest in the position shown, right-of-way being with the main road. If a call is received from the side road by the operation of road-pad N or pedestrian button P, relay E energizes and locks over contacts of cam L. When the cam R of the master control next makes its contacts, relay G energizes so that relay F pulls up to release brake 20 and energize motor 19. Relay F locks to cam H and motor 19 rotates camshaft 21 to drive the lamp signals through a cycle. Relay E is released when cam L opens its contacts but this cam is arranged to close its contacts just before the end of the cross-street " right-of-way period and to hold them closed through the amber and cross-street " red " period so that relay E can lock if re-operated during this time. The apparatus is set so that if no call is received from the cross-street for two cycles of shaft 50, right-of-way is given as soon as a call from the cross-street is made. Wipers 72-74 are moved into position 1 during each cycle of camshaft 21. When cam R next closes its contacts rectifier 64 is energized over wiper 73 so that magnet T operates to step wipers 72-74 one step. After another rotation of cam R wipers 72-74 are again moved so that they are in the position shown and the stepping circuit of magnet T is opened at insulating segment 81. Relay G is now energized over wiper 72 so that when relay E operates relay F is at once energized to initiate transfer of right-of-way. When cam contacts K3, K4 close to give right-of-way to the cross-street, relay U is energized to complete a circuit for rectifier 64 which includes contacts of magnet T and wiper 74 so that magnet T steps wipers 72-74 by self-interruption until wiper 74 reaches its first position. Cams R controlling a number of units may be driven by a single motor or by individual synchronized motors so that " green-wave " conditions are arranged in periods of heavy traffic. Embodiments in which switch T is replaced by a relay chain and by a time delay relay are also described.

Title: Improvements in or relating to electrical counter circuits
Inventor: GUTTRIDGE ERIC JOHN
IPC: H03K23/82
Filed: 1952-03-19
Abstract: 729,751. Electronic counting apparatus. POWERS - SAMAS ACCOUNTING MACHINES, Ltd. Feb. 11, 1953 [March 19, 1952], No. 7145/52. Class 106 (1). In an electrical impulse counter circuit comprising a positive voltage supply lead, first, second, third and fourth bi-stable trigger stages each comprising a pair of anode-to-grid crosscoupled tubes, the first, second and third stages having an input point common to the two tubes and the fourth stage having input points independent to each tube, and a circuit including a coincidence lead connecting the anode of one tube of the fourth stage with the output anode of a selected earlier stage, the output anode of each other earlier stage being connected to the input point for the next succeeding stage with the output anode of the third stage connected to the input point for the other tube of the fourth stage, two " crystal diodes " (which may be selenium rectifiers) are connected in opposite sense in the coincidence lead, and, between the diodes, are a resistor, large in value compared with the output impedance of the trigger circuits, connected to the positive supply lead, and an input lead to the stage next succeeding the selected earlier stage, and a feed forward lead connects the output of the selected earlier stage with the input point of the one tube of the fourth stage through a capacitative filter. The decade counter shown comprises trigger, stages S1, S2, S3, S4, each comprising a pair of triodes T1, T2, of which T2 is conducting in the initial zero condition. Stages S1, S2, S3 have input leads I1, I2, 13 leading to a symmetrical diode buffering arrangement D1, D2, D3. The triodes of stage S4 have separate input leads 141, 142 connected to points S30, S10 in the anode circuits of triodes T2 of S3, S1, respectively. Negative input pulses are applied to I1 and the connections to leads I2, I3 are such that the counter operates in normal binary fashion for the first nine pulses received, the stages S1, S2, S3, S4 representing 1, 2, 4, 8 respectively. Since, however, the eighth pulse triggers S4, a negative potential is applied from point S401 over lead 15 to diode D5 of a coincidence circuit also including diode D4 connected to point S10 and a large resistance connected to H.T. line PL. Thus when triode T2 of S1 next returns to the conductive condition on receipt of the tenth pulse, the resultant negative pulse from S10 will be passed through capacitor C1 to lead 142 to reset S4 and produce negative output pulse from point S40, but will produce little or no effect at point CC so that no effective pulse will be passed by lead I2 to stage S2; all the stages are therefore in their initial condition. A modified decade counter in which the stages represent 1, 2, 4, 2 and similar duodecimal counters in which the coincidence is connected between S4 and S2 (instead of S1) are described. The Provisional Specification refers to Specification 717,780, [Group XL (c)].

Title: Process of separating antimony and lead
IPC: C22B13/06
Filed: 1925-03-17
Abstract: 251,736. Marks, E. C. R., (American Smelting & Refining Co.). March 17, 1925. Dry processes of refining lead.-Crude lead containing antimony in substantial quantities, is refined by maintaining it in fusion in an oxidizing atmosphere, for instance in a reverberatory furnace, at 1200-1700‹ F. At first a skim of tin oxide forms and is removed; then a fume of antimony oxide is liberated and a skim of antimony and lead oxides forms and is removed as long as the fume is produced. By the time the fume is no longer escaping the antimony has been reduced to about 5-7 per cent and the further removal of antimony is effected in the usual manner by skimming until the desired minimum content of antimony is attained. The temperature of the bath is then reduced for instance to 950-1000‹ F. when copper is separated as a skim.
